Gail: The GPM Core, with its ability to detect falling snow,

3
00:00:08,100 --> 00:00:12,120
it's one of the very first times that we've put sensors

4
00:00:12,140 --> 00:00:16,150
in space to specifically look at falling snow. And we're

5
00:00:16,170 --> 00:00:20,180
at that edge where rain was fifty years ago. So

6
00:00:20,200 --> 00:00:24,200
we're still figuring out how to measure snow. Snow is much more

7
00:00:24,220 --> 00:00:28,220
difficult than rain. Rain tends to be spherical-like drops

8
00:00:28,240 --> 00:00:32,230
but if you've ever been out in a snowfall event and you've looked at your shirt

9
00:00:32,250 --> 00:00:36,280
you see that snow comes in all different forms. And the sensors in space

10
00:00:36,300 --> 00:00:40,330
are actually sensitive to those shapes. And we're still

11
00:00:40,350 --> 00:00:44,370
trying to figure out all of that, and the GPM Core, with its

12
00:00:44,390 --> 00:00:48,410
additional frequencies and information on the sensors, is going to be able

13
00:00:48,430 --> 00:00:52,440
to provide us, for the first time, a lot more information about falling snow

14
00:00:52,460 --> 00:00:56,470
than we've ever done before.
